    Exact predictions from Edwards ensemble vs realistic simulations of tapped narrow two dimensional granular columns 

    Irastorza, Ramiro; Carlevaro, Manuel; Pugnaloni, Luis (Journal of Statistical Mechanics: Theory and Experiment, 2013)
    We simulate, via a discrete element method, the tapping of a narrow column of disks under gravity. For frictionless disks, this system has a simple analytical expression for the density of states in the Edwards volume ...

    Contact network topology in tapped granular media 

    Arévalo, Roberto; Pugnaloni, Luis; Zuriguel, Iker; Maza, Diego (American Physical Society, 2013)
    We analyze the contact network of simulated two-dimensional granular packings in different states of mechanical equilibrium obtained by tapping. We show that topological descriptors of the contact network allow one to ...

    Wang Landau algorithm for entropic sampling of arch based microstates in the volume ensemble of static granular packings 

    Slobinsky, Demian; Pugnaloni, Luis (Papers in Physics, 2015)
    We implement the Wang-Landau algorithm to sample with equal probabilities the static configurations of a model granular system. The "non-interacting rigid arch model" used is based on the description of static configurations ...

    Structure of force networks in tapped particulate systems of disks and pentagons I Clusters and loops 

    Pugnaloni, Luis; Carlevaro, Manuel; Kramar, M; Mischaikow, K; Kondic, L (American Physical Society, 2016)
    The force network of a granular assembly, defined by the contact network and the corresponding contact forces, carries valuable information about the state of the packing. Simple analysis of these networks based on the ...

    Clogging transition of vibration driven vehicles passing through constrictions 

    Patterson, G.; Fierens, P.; Sangiuliano Jimka, F.; König, P.; Garcimartín, A.; Zuriguel, Iker; Pugnaloni, Luis; Parisi, D. (American Physical Society, 2017)
    We report experimental results on the competitive passage of elongated self-propelled vehicles rushing through a constriction. For the chosen experimental conditions, we observe the emergence of intermittencies similar to ...

    Experimental proof of faster is slower in systems of frictional particles flowing through constrictions 

    Pastor, Jose; Garcimartín, Angel; Gago, Paula; Peralta, Juan; Martín Gomez, Cesar; Ferrer, Luis; Maza, Diego; Parisi, Daniel; Pugnaloni, Luis; Zuriguel, Iker (American Physical Society, 2015)
    The “faster-is-slower” (FIS) effect was first predicted by computer simulations of the egress of pedestrians through a narrow exit [D. Helbing, I. J. Farkas, and T. Vicsek, Nature (London) 407, 487 (2000)]. FIS refers to ...

    Arch based configurations in the volume ensemble of static granular systems 

    Slobinsky, D.; Pugnaloni, Luis (Journal of Statistical Mechanics: Theory and Experiment, 2015)
    We propose an alternative approach to count the microscopic static configurations of granular packs under gravity by considering arches. This strategy obviates the problem of filtering out configurations that are not ...

    Effect of particle shape and fragmentation on the response of particle dampers 

    Sánchez, Martín; Carlevaro, Manuel; Pugnaloni, Luis (SAGE Publications, 2014)
    A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure. It has been recently suggested that, ...

    On and off dynamics of a creeping frictional system 

    Blanc, Baptiste; Geminard, Jean Christophe; Pugnaloni, Luis (Springer, 2014)
    We report on the dynamics of a model frictional system submitted to minute external perturbations. The system consists of a chain of sliders connected through elastic springs that rest on an incline. By introducing cyclic ...

    A differential equation for the flow rate during silo discharge Beyond the Beverloo rule 

    Madrid, Marcos; Darias, José; Pugnaloni, Luis (EPJ Web of Conferences, 2017)
    We present a differential equation for the flow rate of granular materials during the discharge of a silo. This is based in the energy balance of the variable mass system in contrast with the traditional derivations based ...
